FLY-SCREEN FOR WINDOWS.

SPECIFICATION forming part of Letters Patent No. 579,730, dated March30, 1897. Application filed May 2, 1896.- Serial No. 589,971. (Nomodel.)

To all whmn it may concern.-

Be it known that I, J EDUTHUN N. WIGLE, a subject of the Queen of GreatBritain, residing at Ruthven, county of Essex, Province of Ontario,Canada, have invented a certain new and useful Improvement in aFly-Screen for Windows; and I declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention has for its object a fly-screen for windows of novelconstruction and superior efficiency and also the process ofconstructing the same, whereby flies may readily escape through thescreen from the inside of a room and whereby they may be prevented fromentering a room therethrough.

My invention consists of the structure hereinafter described andclaimed, and illustrated in the accompanying drawings, in which Figure 1is a View in perspective of my improved screen. Fig. 2 is a verticalcross-section thereof, the stiffening-wires a being omitted. Fig. 3 is ahorizontal section on the line 3 3, Fig. 2. Fig. 4 is a detail viewshowing a portion of the screen fabric in vertical section adjacent toone of the stiffening-wires.

The main feature of my invention is in the construction of the screenfabric, my invention contemplating the employment of any suitable frame,although that shown in the drawings is a construction desirable andpreferable for many purposes. I do not, however, limit myself solely toany specific construction of the frame.

In the drawings, A represents my improved screen fabric, preferablyconstructed of wirenetting A having integrally interwoven therewithstiffening wires or rods a of suitable size to afford firmness to thefabric and to hold the fabric in position in a strong and efficientmanner. This fabric A, with the stiffening wires or rods a, ispreferably woven in the fiat and afterward crimped or corrugated, asshown in the drawings, forming verticallyinclined portions A andconnecting portions or, which may be horizontal, as shown, or otherwiseshaped, if preferred. After the fabric has thus been crimped orcorrugated the outer edges of the wire-netting, with the exception ofthe stiffening-wires (1, adjacent to the upper edge of each inclinedportion A, is slitted or cut through to form elongated openings (1 Thestiffening wires or rods aeXtend across said openings a as indicated ata to hold the screen fabric firmly in place. The

wire-netting, with the exception of the stiff- 6o.

ening-rods a, is thus cut into a series of veriically-inclined portionsA with the integral portions a connected therewith. A screen fabric thusmade, with the st-iffeningwires a integrally interwoven in the fabric,then It will readily be seen that flies alighting on the inside ofthe'vertically-inclined portions A of the screen, moving upward, willreadily pass out through the adjacent opening a while the location andarrangement of said openings will tend to prevent the flies fromentering therethrough from the exterior. A fly passing upward on theoutside of one of the vertically-inclined portions A would, as is wellknown of the habits of the fly, pass across the adjacent opening a uponthe adjacent portion a, and so on, instead of turning down through theadjacent opening CF. The stiffening-wires a, when the fabric is crimpedor corrugated, are formed into vertically-inclined portions a andintegral connecting portions a B represents a frame with which thescreen fabric is engaged. Said frame may either be made rigid orexpansible, as may be desired.

As shown in the drawings, the vertical bars B B of said frame areprovided with strips of molding b and b on both its edges, forming achannel between said moldings of sufficient width to take in the lateralcorrugated edges of the fabric, said moldings concealing 5 the edges ofthe fabric. The moldings may set so snugly against the edges of thefabric as to hold the fabric firmly in place. The

upper and lower bars 13 B of said frame are also preferably providedwith strips of molding 11 b on the front and rear faces thereof, whichserve to hold the upper and lower edges of the screen fabric in place.

IVhat I claim as my invention is- 1. In a screen, a fabric formed ofnetting, having a series of vertical rigid stiffening wires or rodsintegrally interwoven therewith, said netting and stiffening wirestransversely crimped or corrugated, the netting being slitted at theouter edges of the corrugations thereof from side to side of the fabricto form continuous openings extending across the fabric, and severingthe wire-netting into a series of independent transverse portions, saidcrimped stifiening wires or rods connecting and supporting the severedportions of the fabric on both sides of each of said slits or openings,and holding said severed portions rigidly together, substantially as setforth.

2. In a screen, afabric constructed of wirenetting having a series ofvertical stiffening wires or rods integrally interwoven there with, saidnetting and stiffening-wires transversely crimped or corrugated, thewire-netting at both sides of said vertical stiffening-rods beingslitted at the outer edges of the corrugations from side to side of thefabric to form continuous transverse openings, and mutiple independenttransverse vertically-inclined portions A and adjacentoutwardly-projecting portions a, said stiffening-rods holding theseveral independent transverse portions of the wire-netting together,for the purpose set forth.

3. In a screen, a fabric constructed of wire netting, provided withvertical rigid stiffening wires or rods, said netting together with saidstiffening-wires being both crimped or corrugated, forming a series oftransverse vertically-inclined portions A, and integral horizontalportions (1/, said wire-netting being slitconstructed of upright andhorizontal por-.

tions, having moldings secured thereto on opposite sides thereof, saidmoldings forming channels on the upright portions of the frameintermediate said moldings to receive the lateral edges of the fabric,said moldings contacting with the horizontal portions a of the fabric tobind the fabric in place, for the purpose set forth.

4. In a screen, the combination of a fabric constructed of wire-nettinghavingaseries of vertical stiffening wires or rods integrally interwoventherewith, said netting and said stiifening-wires transverselycorrugated to form vertically and forwardly inclined portions andsubstantially horizontal portions both of the wire-netting and of thestiffeningwires, the wire-netting being slitted at the outer edges ofthehorizontal portions from side to side of the netting to formcontinuous transverse openings and severing the wirenetting into aseries of independent transverse strips, said strips held together inposition by said stiffening-wires, the horizontal portions of thewire-netting supported upon the horizontal portions of thestiffening-wires, substantially as set forth.

In testimony whereof I sign this specification in the presence of twowitnesses.
